Has anyone ran big all motor cams in a big boosted car?
not like R cams at least skunk stage 2's or bigger.

if so whats the result

P.S. i dont care about what you heard or what you have read. im looking for acual experance.

in my setup last year my car made 480whp @ 20psi on a 60-1 and a toda C intake and stock gsr exaust

 

480whp@20 psi on a 60-1. u coulda probably made around the same power with stock gsr cams.

 

^^^ possibly... I made 348whp @ ~12.5psi on a stock 1st gen b16a w/gsr cams and a 60-1. I'd also like to know the answer to this...

 

blox B's on a 350 WHP setup gave me 15 WHP up top over my ITR's with no tuning

what do you think maz worx cams are simply a slightly more aggresive skunk stage 1/blox stage1/Blox spec A's

are these cams good for a daliy driven turbo car?

 

on a mild mild setup without losing much midrange i'd go with the blox SPec A's PM me for hella good pricing

 

good guy just asking ! for peoples experiences

heres the thing, its not about making the power. its makeing more usable power, hands down a 300whp all motor car vs a 300whp boosted car, you better beleive that all motor car is going to beat the boosted car...but why? its more usable power...all these "boost" cams make impressive numbers but all you here when someone goes down the track is the tires chattering the intire way down...I beleive overlap and some big lobes can really help with the tranistion of power helping with ET.

o yea as for this comment, @ 20psi with smaller ic pipeing on stock gsr cams made 360whp on a dyno jet..

You think someone with 400-600whp spinning the tires is because of "boost" cams? All a aggressive set of cams is going to do is give you more top end and more power. Making it useable is all part of setting up your car, boost in gears, and having a driver who knows the gas pedal isn't a on/off switch.

 

315whp @ 11psi on a conservative tune, holset hy35, 4" to 3" dp, 3" exhaust (including cat), gsr engine, cylinders 20 over, 9.5:1 ish cr, crane stg II na cams. Dunno if y'all consider these cams to be "big all motor cams" so here are the specs and you can decide.......

Primary Lobe Advertised Duration Intake/Exhaust 225 / 225
Secondary Lobe Advertised Duration Intake/Exhaust 245 / 245
VTEC Lobe Advertised Duration Intake/Exhaust 272 / 266
Primary Lobe Duration @ .050 Intake/Exhaust 200 / 200
Secondary Lobe Duration @ .050 Intake/Exhaust 220 / 220
VTEC Lobe Duration @ .050 Intake/Exhaust 248 / 242
Primary Lobe Separation 108 / 108
Secondary Lobe Separation 108 / 108
VTEC Lobe Separation 102 / 108
Primary Lobe Gross Lift 315 / 315
Secondary Lobe Gross Lift 354 / 354
VTEC Lobe Gross Lift 472 / 457


And a dyno sheet to show the power curve.


Hope this helps. GL.

 

1999 B18b at 9.5:1 with 10,000 miles on it. Had Crower 62404 camshafts with a GT3076R @ 14lbs. Made 317whp on a loaded Dyno Dynamics with a crack in the exhaust manifold, slipping RPS clutch and timing coming unsynched at 6600RPM. I'm positive it would have made more without those problems. That's straight off a street tune at a dyno day

 

any more setups?

A 300whp turbo car will walk all over a 300hp n/a car with all other things being equal. The turbo car will have more area under the curve if it's setup right.

 

I run skunk2 stage 2's in my car. Honestly dont think there was a peak power improvment over gsr cams but they made power noticiably earlier (made powerband larger which is always good for a b16).

So your saying at same boost level the toda C intake cam gave 120whp I dont see changing charge piping and cam gaining that...

true story!

 

a large NA cam works perfectly on boosted motors, given you dial out as much overlap as possible.
and actually, some turbo cam profiles are just copies of popular na profiles.

honda motors love big lift and high duration (boosted or na) they just dont like overlap

Are you sure about that?

Equal means both have perfect traction, both have a pro driver used to the car's characteristics, both have the same cams, head, block, crank, tranny, redline etc etc. An NA 1.8L simply can't make the kind of TORQUE a boosted 1.8L will.

Pitting HP against HP is dumb though. You can build 2+ boosted 300whp b-series *cars* for the price of 1 NA 300whp b-series *motor*.

At least with our honda motors. To get 300whp outa a 2litre you're talking super high rpm power and hardly any down low. The turbo motor is at least going to have a midrange. It would destroy it.

Now a 5litre NA 400whp V8 vs a 2litre 400whp turbo 4cyl in the same car and same weight (if that could ever happen) the v8 gonna have a better power band.

liam

 

Although this has nothing to do with the initial subject--In a drag race, especially in the 1/8 mile, and to some extent 1/4 mile the NA car is gonna be super tough to compete against using the same power levels in a boosted setup, given the same car, weight, tires, etc. etc.
I know, your assuing same traction and everything...but that's just the thing..it's not the same traction, and it never will be. The all-motor car is pullin off 1.4 or better 60' on slicks and the turbo car is pullin off 1.8+ 60' times. I've seen and heard of several 275whp+ NA cars running 10's all day long..granted they were stripped down, but I never hear about 280whp turbo Honda's running even close to 10's..maybe high 11's at best, but never in the 10's, even stripped down. Traction.

You can also vouch for NA setups because of the typical gearing of 4.78 or bigger final drive settings. Street turbo cars don't typically run 4.78 due to tire spin in 1st, 2nd, and 3rd gears.

Also, why are NA cars so much harder on axles than turbo cars? Why does a 250whp NA setup equate to as much axle damage as a 500whp turbo setup? Because the NA setup hooks up, which produces lots of stress on the drivetrain while a turbo car is burning the tires right off the wheels. NA cars are able to utilize every ounce of torque in atleast 2nd through 5th gears, as compared to a turbo street Honda w/ 250ft/lbs running into acceleration problems in 1st and 2nd. (where the gear reduction is most detrimental to drivetrain)

Oh yeah, when talking about NA setups..if you use super big NA cams that make power only from 6K-9K, then upgrade your final drive to a 4.78, or 4.90, or even 5.10. This will keep you all up in the powerband where you want to be..and the "power under the curve" situation can only be critiqued on a motor after you've accounted for the gearing being used on the car.

I will say though that a turbo car will easily take an NA car in the longer gears in say a standing mile or half mile race, where traction plays a very small role. I couldn't tell you what would happen on a circuit race/road races but I'd place my bets on the NA cars though, just because they have little overheating issues and great gear reductions for curvy, short acceleration runs.

I can vouche for Joe that is no BS. I saw both dynos.

 

My car pulls consistent 1.57-1.61 60's, on 24.5" tires and at 2450lbs. You're telling me an n/a car at the same weight and on the same tires would pull 1.4's?

These 275whp cars that run 10's, what do they weigh? Have you ever seen someone put a 275hp turbo motor in an all out all motor drag car? You haven't, because if you had, you'd know that it'll run 10's easier than the n/a car...
